this is fun. here’s the PCM signal from my computer’s digital output. it’s nice to watch it flowing by, knowing how the signal is decoded. looks nicely non-distorted too, but the scope isn’t high resolution. someone recently told me that, across the sciences, a wave is a wave is a wave. the understanding that i gained of signal distortion and types of data transmission from some semi-advanced wireless networking classes is rolling over to analog and digital audio. next, i’ll compare the signal output from a cheap and expensive DAC.
